Description and Introduction

Low-Power / Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX483CUA is a low-power RS-485/RS-422 transceiver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX483CUA  
- **Package:** 8-pin µMAX (microMAX)  
- **Supply Voltage Range:** +4.75V to +5.25V  
- **Operating Temperature Range:** 0°C to +70°C (Commercial)  
- **Data Rate:** Up to 250kbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Half-Duplex Communication:** Yes  
- **Low Power Consumption:**  
  - **Supply Current (Quiescent):** 120µA (typical)  
  - **Shutdown Mode Current:** 0.1µA (typical)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Common-Mode Input Voltage Range:** -7V to +12V  
- **Receiver Input Sensitivity:** ±200mV  

### **Descriptions:**  
The MAX483CUA is a low-power, slew-rate-limited transceiver designed for RS-485/RS-422 communication. It features reduced EMI and reflections due to its slew-rate-limited driver, making it suitable for noise-sensitive applications. The device operates from a single +5V supply and includes a low-power shutdown mode for power-sensitive systems.  

### **Features:**  
- **Low-Power Operation:** Ideal for battery-powered systems.  
- **Slew-Rate Limited Driver:** Minimizes EMI and signal reflections.  
- **Half-Duplex Communication:** Supports bidirectional data transmission.  
- **Shutdown Mode:** Reduces power consumption to 0.1µA.  
- **Extended ESD Protection:** Protects against electrostatic discharge.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.  
- **Industry-Standard Pinout:** Compatible with other RS-485 transceivers.  

This information is strictly factual and derived from the manufacturer's datasheet.
